Knut's half-brother is fully adorable

Officials at the Rostock Zoo in Germany say the polar bear was born December 3 but has been cuddling up to his mother, Vilma, in the zoo's birth den for the past two months.

Knut's half-brother obviously got all of the "cute" genes.

This week, he made his first acquaintance with the snow, and zookeepers expect him to make his public debut in March. Until then, fans can watch the zoo's weekly video updates of the cub clumsily finding his bearings -- and footing -- in the nursery alongside his doting mother.

The baby bear is still unnamed; the Rostock Zoo is taking suggestions until March 10. If you have an idea, email presse@zoo-rostock.de.

The newest puffball shares a father with Knut, the polar cub who warmed the world's heart when he was abandoned by his mother at Zoo Berlin in 2006 and then hand-raised by zookeepers.
